VapeShop Comments:

At VapeShop we very much like 26650 battery cells. We believe that 26650 battery cells are ideal for vaping as they offer the large capacity that is convenient for vaporizers in a reasonable form. We found vaporizers using 26650 cells have a smaller and more elegant design over those using 3x18650 or even 2x18650 cells. Unfortunately, they are difficult to get!

Important Usage Recommendations:

  • Fully charge before first use
  • Keep batteries in battery case or insulating material
  • Never short circuit the battery and never keep them with conducting material (metal, etc...)
  • Do not discharge the battery below 2.5 V
  • Do not overcharge the battery above 4.25 V - check the battery after charging to ensure your charger has not overcharged them


  • Lithium-Ion (Li-ion) batteries are sensitive to charging characteristics and may vent or explode if mishandled.
  • Li-ion battery can vent (discharge excessive heat buildup) in order to avoid an explosion. It is a desirable feature on all batteries.
  • Users should educate themselves on Li-Ion rechargeable batteries in charging, discharging, assembly, and the safety steps before purchase and/or use.

For full details regarding Lithium Ion Batteries refer to the Product Information page of the site.

perfect for my application
these are shorter (length wise) than any of my other 26650 batteries and allow me to run an atomizer with a a long protruding 510 pin on my BFM mech.

Try VapeShop you wont be disapointed....
Hi im a California resdident that has been vaping for a few years. This company is exceptional in the literal definition of the word. Orders I swear come in half the time, the batteries I have ordered been perfect and seem strong. Price is perfect considering I feel these batteries did better then off brands and even same in stores.
